skrf.io.general.write

skrf.io.general.write(file, obj, overwrite=True)[source]

Write skrf object[s] to a file.

This uses the pickle module to write skrf objects to a file. Note that you can write any pickl-able python object. For example, you can write a list or dictionary of Network objects or Calibration objects. This will write out a single file. If you would like to write out a separate file for each object, use write_all().

Parameters:

file (file, Path, or string) – File or filename to which the data is saved. If file is a file-object, then the filename is unchanged. If file is a string, an appropriate extension will be appended to the file name if it does not already have an extension.
obj (an object, or list/dict of objects) – object or list/dict of objects to write to disk
overwrite (Boolean) – if file exists, should it be overwritten?

Note

If file is a string, but doesnt contain a suffix, one is chosen automatically. Here are the extensions:

skrf object	extension
`Frequency`	‘.freq’
`Network`	‘.ntwk’
`NetworkSet`	‘.ns’
`Calibration`	‘.cal’
`Media`	‘.med’
other	‘.p’

Note

To make the file written by this method cross-platform, the pickling protocol 2 is used. See pickle for more info.

Examples

Convert a touchstone file to a pickled Network,

>>> n = rf.Network('my_ntwk.s2p')
>>> rf.write('my_ntwk',n)
>>> n_red = rf.read('my_ntwk.ntwk')

Writing a list of different objects

>>> n = rf.Network('my_ntwk.s2p')
>>> ns = rf.NetworkSet([n,n,n])
>>> rf.write('out',[n,ns])
>>> n_red = rf.read('out.p')
